METHOD OF OBTAINING CARBOXYLIC ACID AND ALKALI Russian patent published in 1994 - IPC

Abstract RU 2016636 C1

FIELD: processing solutions. SUBSTANCE: mixture of carboxylic chlorides is conveyed to desalting chamber of multichamber electrodialysis apparatus with alternating cation-exchange and bipolar membranes. Cation-exchange side of the bipolar membrane faces cathode. Apparatus for carrying out the method has elongated passages and small inter-membrane space. The process proceeds at a current density of 110 A/m² and a flow rate through desalting chamber of 1.18-4.5 cm/sec. EFFECT: enhanced efficiency of the method. 1 tbl
